APPENDIX 10-B. NATIONAL ENERGY SAVINGS AND NET PRESENT VALUE 

USING ALTERNATIVE ECONOMIC GROWTH SCENARIOS

10-B.1 INTRODUCTION

This appendix presents national energy savings (NES) and net present value (NPV) 

results using inputs from alternative economic growth scenarios. The scenarios are based on the 

High Economic Growth case and the Low Economic Growth case from the AEO20101.

10-B.2 NES AND NPV RESULTS USING ALTERNATIVE ECONOMIC 

GROWTH SCENARIOS

For each product class, DOE calculated NES and NPV using forecasts of housing starts 

and energy prices from the High and Low Economic Growth cases. As one would expect, the 

NPV results are most favorable using energy prices in the High Growth scenario, and least 

favorable using prices in the Low Growth scenario.
